I wouldn't imagine a functioning state. I mean yes, it would be possible but many of us believe the state is evil and shouldn't exist. If you put a gun to my head (like the state) then I would say make taxes and services provided by the state voluntary. Allow for competition for the services. Let the best service provider win.
People find taxation is theft jarring. I get it. I used to as well. But just because the truth is not accepted by the majority of people or "wouldn't" work doesn't change the fact that in every other situation what the state does would be called theft. The idea that there wouldn't be any other way is frankly absurd. I get it, people have lived their whole lives believing a lie that taxes are morally OK. When you really stop and think it through it isn't.
